On March 23, 1946, Lewis was found dead in his Berkeley laboratory where he had been working with; many postulated that the cause of his death was suicide. After Lewis' death, his children followed their father's career in chemistry, and the Lewis Hall on the Berkeley campus is named after him.
Contents.Biography Early life Lewis was born in 1875 and raised in, where there exists a street named for him, G.N. Lewis Way, off Summer Street.
Additionally, the wing of the new Weymouth High School Chemistry department has been named in his honor. Lewis received his primary education at home from his parents, Frank Wesley Lewis, a lawyer of independent character, and Mary Burr White Lewis. He read at age three and was intellectually precocious. In 1884 his family moved to, and in 1889 he received his first formal education at the university preparatory school.In 1893, after two years at the, Lewis transferred to, where he obtained his in 1896.

After a year of teaching at in, Lewis returned to Harvard to study with the physical chemist and obtained his Ph.D. In 1899 with a dissertation on. After a year of teaching at Harvard, Lewis took a traveling fellowship to Germany, the center of, and studied with at and with at. While working in Nernst's lab, Lewis apparently developed a lifelong enmity with Nernst. In the following years, Lewis started to criticize and denounce his former teacher on many occasions, calling Nernst's work on his heat theorem ' a regrettable episode in the history of chemistry'.
A friend of Nernst's, was a member of the Nobel Chemistry Committee. There is evidence that he used the Nobel nominating and reporting procedures to block a for Lewis in by nominating Lewis for the prize three times, and then using his position as a committee member to write negative reports. Harvard, Manila, and MIT After his stay in Nernst's lab, Lewis returned to Harvard in 1901 as an instructor for three more years. He was appointed instructor in. In 1904 Lewis was granted a leave of absence and became Superintendent of Weights and Measures for the Bureau of Science in,.
The next year he returned to when the (MIT) appointed him to a faculty position, in which he had a chance to join a group of outstanding physical chemists under the direction of. He became an assistant professor in 1907, associate professor in 1908, and full professor in 1911.University of California, Berkeley G. Lewis left MIT in 1912 to become a professor of physical chemistry and Dean of the at the.
On June 21, 1912, he married Mary Hinckley Sheldon, daughter of a Harvard professor of. They had two sons, both of whom became chemistry professors, and a daughter.
In 1913, he joined the at Berkeley, the professional chemistry fraternity.While at Berkeley, Lewis mentored and influenced numerous future Nobel laureates including (1934 Nobel Prize), (1949 Nobel Prize), (1951 Nobel Prize), (1960 Nobel Prize), (1961 Nobel Prize) and so on. Due to his efforts, the College of Chemistry at Berkeley became one of the top chemistry centers in the world. In 1913, he was elected to the. He resigned in 1934, refusing to state the cause for his resignation; it has been speculated that it was due to a dispute over the internal politics of that institution or to the failure of those he had nominated to be elected.
His decision to resign may have been sparked by resentment over the award of the 1934 Nobel Prize for chemistry to his student, for the discovery of, a prize Lewis almost certainly felt he should have shared for his work on purification and characterization of. Death In 1946, a graduate student found Lewis's lifeless body under a laboratory workbench at Berkeley. Lewis had been working on an experiment with liquid, and deadly fumes from a broken line had leaked into the laboratory. The coroner ruled that the cause of death was, because of a lack of any signs of cyanosis, but some believe that it may have been a suicide. Berkeley Emeritus Professor William Jolly, who reported the various views on Lewis's death in his 1987 history of UC Berkeley’s College of Chemistry, From Retorts to Lasers, wrote that a higher-up in the department believed that Lewis had committed suicide.If Lewis's death was indeed a suicide, a possible explanation was depression brought on by a lunch with.
Langmuir and Lewis had a long rivalry, dating back to Langmuir's extensions of Lewis's theory of the chemical bond. Langmuir had been awarded the 1932 Nobel Prize in chemistry for his work on, while Lewis had not received the Prize despite having been nominated 41 times. On the day of Lewis's death, Langmuir and Lewis had met for lunch at Berkeley, a meeting that Michael Kasha recalled only years later. Associates reported that Lewis came back from lunch in a dark mood, played a morose game of bridge with some colleagues, then went back to work in his lab. An hour later, he was found dead. Langmuir's papers at the confirm that he had been on the Berkeley campus that day to receive an honorary degree.Lewis Hall at Berkeley, built in 1948, is named in his honor. Scientific achievements Thermodynamics Most of Lewis’ lasting interests originated during his Harvard years.
The most important was thermodynamics, a subject in which Richards was very active at that time. Although most of the important thermodynamic relations were known by 1895, they were seen as isolated equations, and had not yet been rationalized as a logical system, from which, given one relation, the rest could be derived. Moreover, these relations were inexact, applying only to ideal chemical systems. These were two outstanding problems of theoretical thermodynamics.
In two long and ambitious theoretical papers in 1900 and 1901, Lewis tried to provide a solution. Lewis introduced the thermodynamic concept of and coined the term '. His new idea of fugacity, or 'escaping tendency', was a function with the dimensions of which expressed the tendency of a substance to pass from one chemical phase to another. Lewis believed that fugacity was the fundamental principle from which a system of real thermodynamic relations could be derived.
This hope was not realized, though fugacity did find a lasting place in the description of real gases.Lewis’ early papers also reveal an unusually advanced awareness of and ideas of free energy. These ideas were well known to physicists and mathematicians, but not to most practical chemists, who regarded them as abstruse and inapplicable to chemical systems. Most chemists relied on the familiar thermodynamics of heat (enthalpy) of, and, and the school. Heat of reaction is not, of course, a measure of the tendency of chemical changes to occur, and Lewis realized that only free energy and entropy could provide an exact chemical thermodynamics. He derived free energy from fugacity; he tried, without success, to obtain an exact expression for the function, which in 1901 had not been defined at low temperatures. Richards too tried and failed, and not until Nernst succeeded in 1907 was it possible to calculate entropies unambiguously.
Although Lewis’ fugacity-based system did not last, his early interest in and entropy proved most fruitful, and much of his career was devoted to making these useful concepts accessible to practical chemists.At Harvard, Lewis also wrote a theoretical paper on the thermodynamics of in which he postulated that light has a pressure. He later revealed that he had been discouraged from pursuing this idea by his older, more conservative colleagues, who were unaware that and others were successfully pursuing the same line of thought.
Lewis’ paper remained unpublished; but his interest in radiation and, and (later) in, sprang from this early, aborted effort. From the start of his career, Lewis regarded himself as both chemist and physicist.Valence theory. Lewis' (as drawn in 1902)About 1902 Lewis started to use unpublished drawings of in his lecture notes, in which the corners of the cube represented possible positions. Lewis later cited these notes in his classic 1916 paper on chemical bonding, as being the first expression of his ideas.A third major interest that originated during Lewis’ Harvard years was his valence theory. In 1902, while trying to explain the laws of valence to his students, Lewis conceived the idea that atoms were built up of a concentric series of cubes with electrons at each corner.
This “cubic atom” explained the cycle of eight elements in the periodic table and was in accord with the widely accepted belief that chemical bonds were formed by transfer of electrons to give each atom a complete set of eight. This electrochemical theory of valence found its most elaborate expression in the work of in 1904, but Lewis’ version of this theory was the only one to be embodied in a concrete atomic model. Again Lewis’ theory did not interest his Harvard mentors, who, like most American chemists of that time, had no taste for such speculation. Lewis did not publish his theory of the cubic atom, but in 1916 it became an important part of his theory of the shared electron pair bond.In 1916, he published his classic paper on chemical bonding ' The Atom and the Molecule' in which he formulated the idea of what would become known as the, consisting of a of electrons, and he defined the term odd molecule (the modern term is ) when an electron is not shared. He included what became known as as well as the model.
These ideas on were expanded upon by and became the inspiration for the studies on the nature of the chemical bond by.Acids and bases. Main article:In 1923, he formulated the electron-pair theory of. In this theory of and, a 'Lewis acid' is an electron-pair acceptor and a 'Lewis base' is an electron-pair donor. This year he also published a monograph on his theories of the chemical bond.Based on work by, it was known that chemical reactions proceeded to an determined by the of the substances taking part. Lewis spent 25 years determining free energies of various substances. In 1923 he and published the results of this study, which helped formalize modern.Heavy water Lewis was the first to produce a pure sample of deuterium oxide in 1933 and the first to study survival and growth of life forms in heavy water.
By accelerating (deuterium ) in, he was able to study many of the properties of atomic nuclei. During the 1930s, he was mentor to, who was retained for post-doctoral work as Lewis' personal research assistant.
Seaborg went on to win the 1951 in Chemistry and have the element named in his honor while he was still alive.O 4 Tetraoxygen In 1924, by studying the properties of solutions of in, Lewis found that O 4 molecules were formed. This was the first evidence for.Relativity and quantum physics In 1908 he published the first of several papers on, in which he derived the - relationship in a different way from 's derivation. In 1909, he and combined his methods with. In 1912 Lewis and presented a major work in mathematical physics that not only applied to the study of, but also noted the identity of a spacetime and a.In 1926, he coined the term ' for the smallest unit of radiant energy (light).
Actually, the outcome of his letter to was not what he had intended. In the letter, he proposed a photon being a structural element, not. He insisted on the need for a new variable, the number of photons.
Although his theory differed from the introduced by in 1905, his name was adopted for what Einstein had called a light quantum (Lichtquant in German).Other achievements In 1921, Lewis was the first to propose an empirical equation describing the failure of to obey the, a problem that had perplexed physical chemists for twenty years. His empirical equations for what he called were later confirmed to be in accord with the for strong electrolytes, published in 1923.Over the course of his career, Lewis published on many other subjects besides those mentioned in this entry, ranging from the nature of quanta to the of price stabilization. In the last years of his life, Lewis and graduate student, his last research associate, established that of molecules involves emission of light from one electron in an excited (a state in which two electrons have their oriented in the same direction, but in different orbitals) and measured the of this triplet state.
